PATENT? OFFICE HARRY o; WARNER, orjKeNsAs GITY, MISSOURI HAIR TRIIVIMINGATTACHMENT FOR SAFETY RAZORS fa ncauon filed July 13,

This invention relates to hair trimming attachments for use incombination with the ordinary safety razor'and the primary ob ject ofthe invention is to provide a simple, for the trimming of hair whichincludes means for progressively cutting the hair shorter as the end ofthe stroke is reached.

One of the objects of the invention is the contemplation of a newarticle of Imanufacture in the form of a hair trimming guide for safetyrazors, whlch guide mcludes a plurality of movable members each having acam facethereon, whereby to allow the cut ting edge of the blade toprogressively move toward or from the head as hair isbeing cut.

An even further object of theinvention is to provide a hair trimmingattachment for safety razors which may be easily combined 80 bodiedparts that are strong and durable,

with the well known double-edged safety razor and which may bemanufactured and sold as an accessory, attachable to such safety razorswithout altering the same.

Besides the more specific objects of the invention which will appearduring the course of the detailed specificatiomthe inventioncontemplates an attachment of the above mentioned character wherein isemcheap to manufacture bled. In the drawings:

Figure 1 illustrates and quickly assemthe use of a safety razor and haircutting attachment which is made in accordance with the presentinvention.

2 is an enlarged front view of razor and attachment.

Fig. 3 is an enlarged perspective view of the hair trimming guideshowing the same entirely removed from combination with a safety razor,and,

Fig. 4 is an enlarged vertical cross section through the completelyassembled device, taken on lineIV-IV of Fig. 2. j

Like reference characters designate similar parts throughout the severalviews of the drawings and the numerals 6 and 8 indicate an upper and alower plate respectively of the ordinary well known double-edge along:opposite sides 1931; Serial No. 550,381

safetyrazor, between which plates 6 and 8 is interposed blade 10, havingcutting edges 12 thereof. As is the custom" in razors ofthis' character,a handle 14: is provided to engage a portion of the upper plate 6 and tobear against the lower plate 8, whereby blade 10 is drawn tothe suitablecurve. In some instances a longitudinal rib .16 is formed'along thelower face of plate 8.

As illustrated in'F 3, the attachment proper is formed of a frame 18having a longitudinal slot 20 formed therethrough for the passage'ofdepending neck 22, integral with plate 6. When a rib. 16 forms a part oflower plate 8 it enters slot '20 and the end-of-handle 14: bears againstthe lower face of frame 18 to hold the sameagainst the under side ofplate 8 asillustrated in Fig. 4. A bearing 24is formed adjacent each endrespectively of frame 18, through which passes connecting bar 26. Thisbar 26 is journaled in bearings 24 for pivotal movement and extendsbeyond the bearings Where it supportsthe guides 28. Guides 28 arerigidly mounted upon bar 26 and rotate therewith. Their bearing edges 30are arcuate and serrated and when theattachmentis in place this edge 30is concentric to the cutting edge 12 of blade 10, as shown in Fig. d.

A stop 32 carried by bar 26 engages the 0 under side of frame 18 and aspring 34. coiled about bar 26'yieldably urges guides 28 and bar 26 tothe normal position where stop 32 is functioning. Guide finger 36extends upwardly from frame 18 and terminates there-. above in atransverse plane intermediate movable guides 28. When the attachment isin actual use it is obvious that blade 10 is bedo not press down uponthe hair to interfere with the cutting operation and their positioningbeyond each end of blade 10 is a novel feature which contributes to theefficiency of the device.

As shown in Fig. 2, connecting bar 26 extends beneath the blade andplates of the razor and nothing interferes with the cutting action. Thestabilizing guide member 36 contributes further toward a neat operationand the attachment greatly enlarges the possibilities of any safetyrazor.

Parts of the attachment proper are pref erably made of metal, but may beformed in any suitable fashion so long as the salient features hereinare preserved in the structure.

It is understood that a large number of modifications might be practicedwithout departing from the spirit of the invention or scope of theappended claims.

hat is claimed as new and desired to be secured by Letters Patent is:

1. The combination with a safety. razor having a cutting bladeinterposed between an upper and a lower plate, of a hair trimmingattachment including a pivotally mounted guide at each end respectivelyof said blade, the cutting edge of said blade moving between said guidesas the attachment is operated.

2. The combination with a safety razor having a cutting blade interposedbetween an upper and a lower plate, of a hair trimming attachmentincluding a pivotally mounted guide at each end respectively of saidblade; a cam bearing face formed on each of said guides, the cuttingedge of said blade being positioned between said guides, said cam facesbeing eccentric to said cutting edge whereby the same moves toward andfrom a line connecting said cam faces as the guides are moved abouttheir pivotal mountings.

3. The combination with a safety razor having a cutting blade interposedbetween an upper and a lower plate, of a hair trimming attachmentcomprising a pivotally mounted guide at each end respectively of saidblade and spaced therefrom; a cam bearing face formed on each of saidguides; and means yieldably maintaining. said guides in predeterminedposition with respect to the cutting edge of said blade.

a. The combination with a safety razor having a cutting blade interposedbetween an upper and a lower plate, of a hair trimming attachmentcomprising a pivotally mounted guide at each end respectively ofsaid'blade and spaced therefrom; a cam bearing face formed on each ofsaid guides; and means yieldably maintaining said guides inpredetermined position with respect to the cutting edge of said blade,said means including a connecting bar extendlng between said guidesbeneath said lower plate, a spring mounted upon said bar to impartyielding force thereto, and a movement limiting stop carried by saidbar.

5. The combination with a safety razor having a cutting blade interposedbetween an upper and a lower plate, of a hair trimming attachmentcomprising a pivotally mounted guide extending transversely of saidblade at each end thereof; a connecting bar joining said guides beneathsaid blade; a retrieving spring mounted upon said bar; and a movementlimiting stop carried by said bar to limit rotary movement thereof.

6. As a new article of manufacture, a hair trimming guide for safetyrazors comprising a frame; a bearing at each end thereof; a connectingbar journaled in said bearings; a cam-shaped guide mounted upon saidbar; and means yieldably maintaining said guides in predeterminedposition relative to said frame.

7. As a new article of manufacture, a hair trimming guide for safetyrazors comprising a frame; a longitudinal attaching slot formed in saidframe; a movable guide at each end respectively of said frame; and astationary guide finger terminating in spaced relation to said frame andbetween said movable guides.

8. As a new article of manufacture, a hair trimming guide for safetyrazors comprising a frame; an attaching slot formed by said frame; arotatable guide at each end respectively of said frame, extendinglaterally from one side thereof; and a stationary guide fingerprojecting from'said frame at the oppo site side thereof and terminatingin atrans verse plane intermediate said guides.

9. As a new article of manufacture, a hair trimming guide for safetyrazors comprising a frame; an attaching slot formed longitudinally ofsaid frame; a depending bearing integral'with the said frame at each endrespectively thereof; a connecting bar journaled in said'bearings forrotation; a guide having an arcuate bearing face mounted on said baradjacent each of said bearings respectively; a spring coiled upon saidbar intermediate said bearings; and a stationary guide finger integralwith said frame.

In testimony whereof, I hereunto affix my signature.
